Diabetes is not just a health issue, but a disease which concerns the whole of society, according to a spokesperson from the World Health Organisation (WHO).

Changes in life-style in countries across the world are resulting in more cases of the sometimes fatal condition.

Around 422 million people now suffer from diabetes, a figure which has almost doubled in the past 35 years.

On World Diabetes Day marked annually on November 14, WHO’s Fadela Chaib began by explaining to Priyanka Shankar about the main types of diabetes.
